Heat guns are normally relegated to evaporating solvent from a TLC plate and developing reactions with visualizing reagents like phosphomolybdic acid
Colorimetry of total phenolics with phosphomolybdic acid
phosphotungstic acid reagents.
In order to perform PRAP assays on the samples, each dilution was mixed 10% phosphomolybdic acid
solution in ethanol (w/v) .
Deokar, "An environmentally benign one-pot synthesis of 1,2 dihydro-1-arylnaphtho[1,2-e][1,3]oxazine-3-one derivatives catalysed by phosphomolybdic acid

Differentiate in Stain in Ponceau de phosphomolybdic acid
1%: xylidine 1%: 1-5 min.
Total Antioxidant Capacity (Phosphomolybdic Acid
The Folin-Denis reagent was prepared by mixing 100 g sodium tungstate, 20 g phosphomolybdic acid
and 50 ml phosphoric acid with 750 ml water.
USA); and phosphomolybdic acid
was obtained from BDH, Dorset, UK.
The latter is not possible if the total phenolic compounds are quantified with the Folin-Ciocalteu reagent, as this method is based on the reduction of the phosphomolybdic acid
by the phenolic compounds and therefore, other reducing compounds could be detected.
The inorganic phosphorus concentration of serum was measured using the phosphomolybdic acid
method (Fiske and Subbarow, 1925).
Potassium hydroxide was from Chemapol, Checkoslovakia; manganese(II)chloride, sulphuric acid, and phosphomolybdic acid
were from Reakhim, Russia.
